When the screen is off, there are no guarantees about when non-wakeup alarms will be dispatched. Historically they are dispatched any time the device wakes up. With this change, we will delay the dispatch until sometime later. The amount of delay is determined by how long the screen has been off. Currently there are three possible delays: up to 2 minutes if the screen has been off for less than 5 minutes; up to 15 minutes if it has been off for less than 30 minutes; and otherwise up to an hour. When the screen is turned on or a wakeup alarm is dispatched, all delayed alarms will also be dispatched. Note that one of the things this delays is TIME_TICK, which means the in many cases we won't deliver TIME_TICK until the screen is in the process of waking up. The current implementation causes this to be delayed until the SCREEN_ON broadcast is sent; we probably want to improve this to have the power manager tell the alarm manager about the screen turning on before it sends that broadcast, to help make sure things like the lock screen can update their current time before the screen is actually turned on. In addition, switch all of the alarm stats to use the new PendingIntent "tag" identifier for its operations, instead of the old code to try to construct a pseudo-identifier by retrieving the raw Intent. Also add a new package manager command to immediately write packages.xml. Change-Id: Id4b14757cccff9cb2c6b36de994de38163abf615
